A new conservative method for the treatment of phimosis is presented: similar to the labio-synechia of girls a local treatment with an oestrogen containing cream is performed successfully. After approximately three weeks about 90% of the boys could easily retract their prepuce. We hope that in future an operation will be less often necessary because of this successful conservative method.
